The EZER™ Dengue IgG/IgM Rapid Test is a qualitative lateral flow immunoassay designed to detect Dengue IgG IgM antibodies in human whole blood, serum, or plasma. It is intended for rapid differentiation between primary and secondary Dengue virus infections, particularly during the early stages of clinical presentation.
By detecting IgM antibodies (indicative of primary infection) and IgG antibodies (associated with secondary or past infection), this test provides important diagnostic insights for managing dengue cases. The dual-marker approach supports timely treatment decisions, especially in endemic regions where multiple serotypes circulate.
The test delivers results within 10 minutes, using only 10 µL of sample and 2 drops of buffer. A clear band appears in designated zones for IgG (G), IgM (M), and control (C). With an overall accuracy of 99.4%, the EZER™ Dengue IgG/IgM Rapid Test offers high confidence in serological screening, whether in centralized labs or field settings.
This diagnostic solution is manufactured by Genesis Biotech and validated against commercial ELISA methods, showing sensitivity >97% and specificity 100% for both IgM and IgG.
Each kit includes:
20 test cassettes with G, M, and C lines
20 calibrated plastic droppers (10 µL)
1 buffer solution tube
1 instruction leaflet (package insert)
The test identifies the presence of IgM (M line) and IgG (G line) antibodies. The control (C line) confirms proper sample migration. This allows for rapid distinction between ongoing and past Dengue infections.
Dengue IgG IgM antibodies represent the body’s immune response to Dengue virus infection:
IgM-positive: Typically indicates a recent or primary dengue infection, often in the first 5–7 days post-exposure.
IgG-positive: Often indicates a secondary infection or past exposure. Levels tend to rise quickly during reinfection.
Both IgG & IgM-positive: Suggest a recent secondary dengue infection, usually associated with more severe clinical outcomes.
By detecting both antibody classes, this rapid test supports better triage and patient risk stratification in outbreak and endemic scenarios.
This test uses dengue-specific antigens immobilized on a nitrocellulose membrane, designed for antibody capture. During testing:
The patient sample is applied to the sample well
Capillary action draws the sample across the membrane
If Dengue-specific IgG and/or IgM antibodies are present, they bind to colored antigen particles and form visible lines at the G and/or M test regions
IgM Sensitivity: 97.1%
IgG Sensitivity: >99.0%
Specificity: 100%
Overall Accuracy: 99.4%
Whole blood (EDTA, citrate, or heparin)
Serum
Plasma
No cross-reactivity was observed with other flaviviruses or infectious markers, ensuring high diagnostic reliability.
Allow test and sample to reach room temperature (15–30°C)
Add 10 µL of specimen using the provided dropper
Add 2 drops of buffer
Wait 10 minutes before reading results
IgM positive: Band in region M + C
IgG positive: Band in region G + C
IgG & IgM positive: Bands in G, M, and C regions
Negative: Only control line (C) visible
Invalid: No C line – retest required
Results beyond 20 minutes should not be interpreted due to possible false positives.
The EZER™ Dengue IgG/IgM Rapid Test is a reliable frontline tool for:
Differential diagnosis during acute febrile illness
Epidemiological surveillance in dengue-endemic areas
Triage decision-making in emergency care
Outbreak management and seroprevalence screening
This test supports rapid response in healthcare settings with limited resources and can complement NS1 antigen testing to capture a broader diagnostic window.
